For the most part this level of microservice solves the problem of: New engineering leader comes in. New engineering Leader wants to rewrite the entire thing cause "it sucks". Business doesn't have resources to rewrite (for the nth time). New leader and business compromise to create a microservice. Rinse and repeat. Cloud/container/VM tech as really allowed this pattern to work. The art of taking over an existing codebase, keeping it going at low cost, low overhead is gone. Nobody's promo packet is fulled with sustainment work. One microservice per promotion. Etc etc.
